A graph is planar if it can be drawn on a plane so that the edges intersect only at the vertices. (For example, of the five first complete graphs all but the fifth, K, is planar.)
Attribute of a graph. A graph is called planar, if it can be drawn in the plane such that there are no edge crossings.
A planar graph is a graph that you can draw on a flat surface, or plane, without any of the edges crossing. Graphs that cannot be drawn on the plane without crossed edges are called non-planar graphs. Any graph that has either of the following graphs as subgraphs are non-planar
Of, pertaining to or contained in a single geometric plane.
A simple flat capacitor built between silicon and polysilicon layers.
any flat surface diaphragm driver typically film based, electrostatic, Ribbon types.
In nuclear medicine, it provides a two-dimensional view of the organ being imaged.
Any being native to a plane other than the Prime Material Plane. These are living beings, not petitioners.
Flat, or in a single plane; as opposed to stereoscopic or three-dimensional.
